2、工科大学生理论联系实际、敢于动手、善于动手和独立自主解决设计实践中遇到的各种问题能力的一个重要教学环节。通过课程设计，要求学生熟悉和掌握微机系统的软件、硬件设计的方法、设计步骤，使学生得到微机开发应用方面的初步训练。让学生独立或集体讨论设计题目的总体设计方案、编程、软件硬件调试、编写设计报告等问题，真正做到理论联系实际，提高动手能力和分析问题、解决问题的能力，实现由学习知识到应用知识的初步过渡。通过本次课程设计使学生熟练掌握微机系统与接口扩展电路的设计方法，熟练应用 8086 汇编语言编写应用程序和实际设计中的硬软件调试方法和步骤，熟悉微机系统的硬软件开发工具的使用方法。通过课程设计实践，不仅
3、要培养学生事实求是和严肃认真的工作态度，培养学生的实际动手能力，检验学生对本门课学习的情况，更要培养学生在实际的工程设计中查阅资料，撰写设计报告表达设计思想和结果的能力。3二、 设计内容利用点阵屏显示汉字三、 设计要求（1） 通过四个 8*8 点阵组成 16*16 点阵屏（2） 一个 16*16 点阵显示多个汉字（3） 多个汉字循环在点阵屏上显示四、 设计原理LED 阵列的显示方式是按显示编码的顺序，一列一列地显示。每一列的显示时,由于人类的视觉暂留现象，将感觉到一列 LED 是在同时显示的。若显示的时间太短，则亮度不够，若显示的时间太长，将会感觉到闪烁。本文采用低电平逐列扫描，高电平输出显示
